I would use brass valves outside too.
If you wanted to trick it out you could install a before and after gauge.
I need some suggestions on dealing with this water service entrance.
The incoming supply is one inch Pex. The PRV is a Watts, which does not seem to be regulating well. It is mounted too close to the wall to remove without prior disassembly. The copper transitions to Pex at the top of the wall above the PRV and feeds the rest of the house.
The lower mounting board is loosely fastened to the concrete wall on only one side. The other side is completely free. The whole thing would fall down if it weren't for the pipe itself.
The incoming line penetration is through 14 - 16 inches of poured concrete about four foot below grade. It connects to a 3/4" water meter about 1/4 mile away. Allegedly, the line transitions to 2" pipe between the one inch Pex and the 3/4" port on the meter. Supposedly, the pipe is PVC, but I have my doubts about both the size and its composition.
Right now I have no way to read the pressure on the line before the PRV. This seems essential to me. I would also like to add some yard hydrants without another penetration in the wall. I am thinking of putting a T connector in the one inch Pex outside the house and routing each branch through a shutoff. One would come into the house and the other would feed the yard hydrant line. I would also clean up the inside part of the installation.
Does this sound like a good plan, and what kind of shutoffs would be appropriate? I have used plastic ball valves outside in the past, but I don't really like them. I much prefer brass/bronze valves. I just don't know if they are suitable for exterior use. The ground here is clay, and I would mount the valves below the frost line with access through a box of some sort.
I can sweat copper and have worked with Pex before.
Any comments or suggestions?

Are you sure that's 1" PEX? It looks like 3/4 and the copper looks like 1/2

I just got back to digging up the pipe. I found the alleged 2" PVC. It is actually 1.5 inch pipe. The transition to 1" Pex is 15 feet from the house.
Here's my question.
I plan on installing a couple garden hydrants and a shutoff. I have essentially two choices.
1. Put a Tee in the 1.5" PVC.
2. Cut into the 1" Pex, insert a Sharkbite 1" to 3/4" transition piece somewhere in that 15' run, then Tee into the 3/4 Pex for the rest of the run to the house and the garden hydrants.
I am equipped to work with 3/4 Pex, but not the 1" stuff, and I don't want to buy a tool just for that 15 foot section.
